Abstract Background The Collaboration for Evidence-based Healthcare and Public Health in Africa (CEBHA+) is a research consortium concerned with the prevention, diagnosis treatment of non-communicable diseases. CEBHA+ seeks to engage policymakers practitioners throughout process order build lasting relationships, enhance evidence uptake, create long-term capacity among partner institutions Ethi...
The COVID-19 outbreak began at the end of 2019, and has evolved to a pandemic threatening various industries’ sustainability. Decisive actions have been taken tackle pandemic’s spread, however, impacts continue be felt by many industries, including construction industry. This paper therefore focuses on outbreak’s impact Quantity Surveyors’ (QS) projects activities, as key profession in A mixed ...
In the real world clustering problems, it is often encountered to perform cluster analysis on data sets with mixed numeric and categorical values. However, most existing clustering algorithms are only efficient for the numeric data rather than the mixed data set. In addition, traditional methods, for example, the K-means algorithm, usually ask the user to provide the number of clusters. In this...
The set covering problem (SCP) is a well-known combinatorial optimization problem. This paper investigates development of a local branching approach for the SCP. This solution strategy is exact in nature, though it is designed to improve the heuristic behavior of the mixed integer programming solver. The algorithm parameters are tuned by design of experiments approach. The proposed method is te...
Introduction: Employing exclusively electronic learning is not possible for practical and clinical courses. But, using a combination of different educational approaches seems to be sensible. The aim of this study was to compare the effectiveness of mixed method of electronic and small group education with that of small group only method. Methods: Seventy two students of Introductory Clinical ...
this research presents a new application of the cloud theory-based simulated annealing algorithm to solve mixed model assembly line sequencing problems where line stoppage cost is expected to be optimized. this objective is highly significant in mixed model assembly line sequencing problems based on just-in-time production system. moreover, this type of problem is np-hard and solving this probl...
